small matrix in big matrix

I want to put a small matrix (p*q) called B into a bigger matrix (m*n) called A. How can I do it. Matrix B should be put on the left-right corner of matrix A.

Why do you post this when you had a better version of this question already posted at http://www.mathworks.com/matlabcentral/answers/77743-put-a-small-matrix-in-a-bigger-one 40 minutes earlier. Please don't duplicate questions. I already answered there for you.

I don't know what "left-right corner" means, but in general you can do this as:

A = magic(7);
B = magic(3);

A(2:4,3:5) = B;
